Sun(sm) Alert Notification

     * Sun Alert ID: 102779
     * Synopsis: Security Vulnerability in the Sun Ray Server Software 
Admin GUI
     * Category: Security
     *
       Product: Sun Ray Server Software 3.0, Sun Ray Server Software 2.0
     * BugIDs: 4950642
     * Avoidance: Patch
     * State: Resolved
     * Date Released: 23-Jan-2007
     * Date Closed: 23-Jan-2007
     * Date Modified:

1. Impact

Due to a security vulnerability in the Sun Ray Server Software, an 
unprivileged local user may be able to intercept the Sun Ray 
administrator's (utadmin) password when the administrator logs in to the 
Sun Ray Administration Tool.

In addition, a user who obtains read access to the Sun Ray private web 
server's logfile, or to a similar logfile on a proxy server, can extract 
the Sun Ray administrator's (utadmin) password. This would allow the 
user to gain unauthorized access to the Sun Ray Server Software with the 
privileges of the utadmin user.
2. Contributing Factors

This issue can occur in the following releases:

SPARC Platform

     * Sun Ray Server Software 2.0 (for Solaris 8, 9) without patch 
114880-10 
(http://sunsolve.sun.com/search/document.do?assetkey=urn:cds:docid:1-21-114880-10-1)

     * Sun Ray Server Software 3.0 (for Solaris 8, 9, 10) without patch 
118979-02 
(http://sunsolve.sun.com/search/document.do?assetkey=urn:cds:docid:1-21-118979-02-1)

Linux Platform

     * Sun Ray Server Software 3.0 (for JDS R2, RHELAS 3.0, SLES 8.0) 
without patch 119836-02 
(http://sunsolve.sun.com/search/document.do?assetkey=urn:cds:docid:1-21-119836-02-1)

To determine the version of the Sun Ray Server Software on a Solaris 
system, the following command can be run:

     # /usr/bin/pkginfo -l SUNWuto | grep -i version
     VERSION: 3.1_32,REV=2005.08.24.08.55

To determine the version of Sun Ray Server Software on a Linux system, 
the following command can be run:

     # /bin/rpm -q SUNWuto
     SUNWuto-3.1-32.21

Notes:

    1. Sun Ray Server Software 3.1 and Sun Ray Server Software 3.1.1 are 
not affected by this issue.
    2. This issue can occur both when the Sun Ray web administration GUI 
is configured to use SSL, and when it is configured not to use SSL.
    3. Sun Ray Server Software 1.0, 1.1, 1.2 and 1.3 will not be 
evaluated regarding the potential impact of the issue described in this 
Sun Alert document.

3. Symptoms

If the Sun Ray server has been affected by the issue described in this 
Sun Alert, the password may appear in the log file of the web server 
that is in use.

To determine if a Sun Ray server has been affected by this issue, check 
the web server logfile as follows:

1. Open the web server logfile in an editor.

2. Use the editor's functionality to search for the Sun Ray 
admininistrator's (utadmin) password.

Note: Do not use "grep" to search for the utadmin password, as this 
might cause the password to be visible in the process list for a very 
short time, and to be logged to your shell's history.

On Sun Ray Server Software 3.0, the logfile location is defined in 
httpd.conf. The location of the httpd.conf file is stored in the 
utadmin.conf file:

On Solaris:

     # /usr/bin/grep http.cfile /etc/opt/SUNWut/utadmin.conf
     admin.http.cfile   = /etc/apache/httpd.conf

In httpd.conf:

     CustomLog /var/apache/logs/access_log common
     ErrorLog /var/apache/logs/error_log

On Red Hat Linux Advanced Server Release 3:

     # /bin/grep http.cfile /etc/opt/SUNWut/utadmin.conf
     admin.http.cfile  = /etc/httpd/conf/httpd.conf

In httpd.conf:

     CustomLog logs/access_log common
     ErrorLog logs/error_log

The default location of the logfiles is "/var/log/httpd/access_log" and 
"/var/log/httpd/error_log".

On SuSE Linux Enterprise Server 8:

     # /bin/grep http.cfile /etc/opt/SUNWut/utadmin.conf
     admin.http.cfile   = /etc/httpd/conf/httpd.conf

In httpd.conf:

     CustomLog /var/log/httpd/access_log common
     ErrorLog /var/log/httpd/error_log

The default location of the logfiles is "/var/log/httpd/access_log" and 
"/var/log/httpd/error_log".

On JDS 2:

JDS 2 does not provide an Apache web server by default. Use the 
following to identify the location of the httpd.conf:

     # grep http.cfile /etc/opt/SUNWut/utadmin.conf

On Sun Ray Server Software 2.0, the web server logfiles are located in 
the following directory:

     /var/opt/SUNWut/http/utadmin/websites/default_site/logs/

Solution Summary
4. Relief/Workaround

To work around the described issue, do the following (use the command 
line tools rather than the Sun Ray web administration GUI):

1. To ensure that nobody else uses the web administration GUI, remove 
the execute permissions from the "main" binary:

     # chmod a-x /opt/SUNWut/cgi-bin/main

To undo the workaround:

     # chmod a+x /opt/SUNWut/cgi-bin/main

2. Ensure that only the root user has read access rights to the web 
server logfiles by changing the permissions of those files using a 
command such as chmod(1) as required. By default:

     * with Sun Ray Server Software 3.0/Solaris, using Solaris bundled 
Apache, the web server logfiles are world-readable.
     * with Sun Ray Server Software 3.0/Linux, using Apache, the 
directory containing the web server logfiles is accessible for the root 
user only.
     * with Sun Ray Server Software 2.0 and earlier, the web server 
logfiles are accessible for the root user and group "other" only.

3. Change the Sun Ray administrator's password by doing the following:

     # /opt/SUNWut/sbin/utpw
     Enter new UT admin password:
     Re-enter new UT admin password:
     Enter old UT admin password:

     Changing LDAP password...
     Done.
     Changing password file...
     Done.

Note: If this server is part of a failover configuration, please run 
utpw(1M) on all servers.

4. If you have used the Sun Ray administrator's password for other 
purposes, change that password as well.

5. Resolution

This issue is addressed in the following releases:

SPARC Platform

     * Sun Ray Server Software 2.0 (for Solaris 8, 9) with patch 
114880-10 or later
     * Sun Ray Server Software 3.0 (for Solaris 8, 9, 10) with patch 
118979-02 or later

Linux Platform

     * Sun Ray Server Software 3.0 (for JDS R2, RHELAS 3.0, SLES 8.0) 
with patch 119836-02 or later

Note: The above patch revisions do not clean up old logfiles, and they 
do not re-render pages which have already been displayed in your 
browser. After patch installation it is recommended that the 
administrator password be changed (using the method described in section 
4, Relief/Workaround). In addition, before logging into the Sun Ray web 
administration GUI, users should either restart the browser or hit 
shift-reload on the GUI's login screen.
